Title: A damper and a door handle incorporating such a damper
Inventor: HAYASHI KEN
IPC: E05B85/18
Filed: 2005-01-26
Abstract: A damper 12 for a door handle comprises a rotor 50 and a valve 56 which are completely separated and only the rotor 50 rotates, so that it is possible to significantly reduce the torque applied to the rotor 50.

Title: Managing conflicting read and write operations on separate read and write buses
Inventor: MIDDLETON PETER GUY
IPC: G06F13/36
Filed: 2005-03-04
Abstract: A bus transaction buffer 34 receives read and write requests on a read bus 38 and a write bus 36 respectively from devices such as processor cores, direct memory access circuits and other bus transaction buffers. It issues read and write requests on a second read bus 42 and write bus 40 to devices such as memories, memory mapped peripheral circuits and other bus transaction buffers. When the buffer receives a read request for an address that has an outstanding write request, the read request is either delayed until the write request completes or completed using the buffered write value 44. The buffer may signal that a write request has completed before it has received a signal indicating the completion of the request. The buffer may produce request acknowledgement signals. The buffer may re-order bus transactions.

Title: Resist exposure and patterning process
Inventor: AFSHAR-HANAEE NASER
IPC: H01L21/027
Filed: 2006-09-19
Abstract: A method is disclosed for forming a multi-layer resist structure on a substrate having a controlled and pre-determined amount of undercut or overcut according to whether a positive or negative tone resist is used. The amount of undercut or overcut is controlled by means of a predetermined level of pre-exposure of each underlying resist layer prior to deposition of the next resist layer and the final patterning of the top resist layer. The multi-layer resist is then developed to remove resist in a controlled manner from each layer according to the degree of exposure of the resist. Using the technique, multi-layer resist structures having very fine sub-micron details are formed. Multi-layer positive tone resist structures can be employed as a mask and combined with metal deposition and lift-off techniques for fabricating very high resolution metallic features.

Title: Multicarrier receivers and methods for detecting cyclic prefixes having
Inventor: QIU SIGANG
IPC: H04L27/26
Filed: 2005-09-29
Abstract: A multicarrier receiver determines the length of a cycle prefix. The multicarrier receiver contains a cyclic prefix detector. The cyclic-prefix detector includes a matched filter to apply first reference data corresponding to a portion of a first training symbol to the sampled received multicarrier communication signal to generate a first detection output. A second reference data corresponding to a portion of a second training symbol is then applied to the sampled received multicarrier communication signal to generate second detection output. The cyclic prefix detector determines the length of a cyclic prefix by performing a modulo operation (eg. modulo by 64) on a number of time-domain samples from first detection output to second detection output. If the longest possible prefix is 64 samples long and the result of the modulo operation by 64 (i.e. the remainder when the number of samples between the two peaks is divided by 64) is zero, then the prefix is 64 samples long. If the result is 32, then the prefix is 32 samples long etc. The cyclic prefix detection circuitry verifies that the time instance of the second detection output is within a predetermined valid range prior to performance of the modulo operation to determine the length of the cyclic prefix. Cyclic-prefix detector may also generate frame-boundary and timing information.
